The Tadano Demag GmbH , formerly Terex Cranes Germany GmbH is a German subsidiary of the Japanese crane manufacturer Tadano . The company builds mobile cranes with a lifting capacity of 30–3,200  tonnes on a 94,482 m² factory site in Zweibrücken, Palatinate .

In addition to the main plant, there is also a branch at Zweibrücken airfield ( Wallerscheid plant ). Another part of the factory in Bierbach was given up in 2017 and sold to the Trier crane company Steil.

The company founded by Christian Dingler in 1827 as Dinglerwerke has been part of Demag since 1954 . After the takeover by Terex in 2002, the purchaser temporarily used the brand name Terex-Demag . Since the takeover by Tadano in 2019, the brand name has been Tadano Demag .

The broad portfolio is now divided into three main areas, the truck- mounted city ​​cranes with a maximum load capacity of 30 to 70 tons, all -terrain military cranes and lattice boom crawler cranes with maximum load capacities of 300 to 3,200 tons, depending on the model.

When it comes to large crawler cranes, the company and its competitor Liebherr enjoy an exceptional position worldwide, as they did during his time at DEMAG.

Company history

The Dinglerwerke: mills, sawmills, printing presses, steam engines

The Dinglerwerke were founded in 1827 as a mechanical workshop in the old town of Zweibrücken. Christian Dingler started with the production of oil and cutting mills with ten workers . From 1834 he also started manufacturing book printing presses . The toggle press developed by Dingler , which he himself called the "Zweibrücker press", went down in the history of printing as the "Dingler press". This machine was a leader in Europe for years and the cause of the company's rapid growth.

In 1834 he acquired the Schönhof estate and moved the factory to the new site in the suburbs, which offered great expansion opportunities. In 1838 he added an iron and metal foundry and his own steam engine plant to the factory, the first in the Palatinate. From 1843 he also began to build steam engines (balancing machines). With these machines, too, he achieved a technically leading position. By 1927, the Dingler-Werke had built over 3,300 steam engines with a total output of around 260,000 hp.

In 1848, Professor L. Seelinger was appointed technical director of the Augsburg Polytechnic School . A large forge with welding furnace and 40 hundredweight hammer was built under his direction . He started making water wheels and turbines .

In 1890, the Dinglerwerke began manufacturing lifting devices for local mining and steel works .

In 1897 the company was transformed into a stock corporation under the name "Dingler'sche Maschinenfabrik Akt.-Ges., Maschinenfabrik, Eisengießerei, Kesselschmiede ...".

In the Velsen mine at the Gustav-II-West shaft, the winding machine, built in 1916/17, is the oldest steam-driven conveyor unit in the Saar district, a product of the Zweibrücker Dingler-Werke. The twin engine was rebuilt in 1936, its rated power is 2400 hp.

In 1930 the Dingler-Werke started manufacturing cranes.

On November 28, 1935, the AG was renamed to Dinglerwerke Aktiengesellschaft Zweibrücken .

During the Second World War , the Dingler works were partially relocated to the Fürst-Stolberg-Hütte in Ilsenburg (Harz) to manufacture submarine parts .

Between the late 1920s and 2007, the Dinglerwerke (from 2003 under the company name TLT-Turbo) supplied turnkey wind tunnels.

In 1944/1945, the Dingler-Werke built a large transonic wind tunnel in the mountain under the code name “Zitteraal” in the Ötztal . Water from the Ötztaler Ache was to be conducted through a tunnel to a water turbine, which was to generate the drive power of 88,000 kW for the wind tunnel at the foot of a mountain. The facility was dismantled by the French in August 1945 and rebuilt in Avrieux near Modane .

In the Delbrück II shaft in Klarenthal , a Dingler winder from 1949 has been preserved.

Demag: cranes

In 1954 Demag AG took over the Dinglerwerke. The activities were integrated into the construction machinery group.

The first telescopic mobile crane with a lifting capacity of 2.5 t was built in 1950 .

In 1976 the plant presented its first crawler crane , the CC 1200 lattice boom crane . A new type of crane followed every year until 1981.

The most successful was the CC 4000 with a basic load capacity of 500 tons, which was used worldwide in large infrastructure projects and large industrial construction projects. The basis of the success was the hydrostatic drive, the stable lattice mast tubes made of fine-grain steel , the jibs and the superlift and ring lift equipment.

The basic load capacity of 500 tons of the CC 4000 and CC 4800 could be increased to 650 tons by using a counterweight of 180 tons directly on the crane. Using a superlift device, a counterweight of 480 tons on a trailer, the load capacity increased to 800 tons, when used with a ring lift to 1,600 tons. The main boom was 102 meters long.

Takeover by Terex during the dissolution of Demag

In 2002, the Terex Corporation acquired the Zweibrücken plant from Siemens , which had taken over this and other plants together with Bosch from Vodafone , in whose hands Demag had come under the Mannesmann takeover (Mannesmann was Demag's parent company), and divided it up joins its Terex Cranes division.

In 2002 the CC 8800 with a load capacity of 1,250 t was introduced. In 2003, a 200 ton all terrain crane with a 68 m main boom was introduced. In 2007 the world's most powerful crawler crane, the TWIN CC 8800, with a lifting capacity of 3,200 t was introduced.

In 2016 the brand name Demag was reintroduced.

In 2019, the Japanese crane manufacturer Tadano took over the company, which has operated as Tadano Demag GmbH since then .

Special crane for the construction of wind turbines

The now mostly very large wind turbines are now almost exclusively built with crawler cranes. After the wind turbine has been set up, the cranes are dismantled and transported to the next wind turbine construction site. Terex developed the CC 2800-1 NT especially for this purpose. NT stands for "Narrow Track", i. H. "Narrow gauge". After being reassembled after delivery by truck, the CC 2800-1 NT can drive from wind turbine to wind turbine within a wind farm on paths that are only 5 m wide. This saves multiple dismantling, transport and reconstruction of the crane within a wind farm and significantly more systems can be erected in the same period.
